Abstract
The invention belongs to machinery industry field, sealing effect is reached for relying on thread locking power and material deformation pretightening force between part, the invention provides a kind of for the seal arrangement in liquid environment, comprise connection spiral shell, sealing spiral shell, Delay Tube, center tube and fill, rely on Delay Tube and the locking force that is threaded being connected spiral shell and being spirally connected, sealing spiral shell be connected the material deformation pretightening force that spiral shell screws extruding center pipe by screw thread and reach seal isolation effect, effective solution cannot be loaded larger Sealing and seal limited structure in the confined space, effective insulation blocking can be implemented to inner member, be particularly useful for the sealing of water base grenade center blast assembly.
Description
Technical field
The invention belongs to machinery industry field, be specifically related to a kind of for the seal arrangement in liquid environment.
Background technique
Higher to sealing requirements for the device be long-term stored in liquid environment, especially do not having abundant space in the device loading Sealing, sealing technique difficulty is larger.Product, in the processes such as packaging, turnover, transport, maintenance and use, is inevitably subject to the impact of extraneous vibration, causes sealability to decline.
In view of the foregoing, how to develop a kind of to can be used in liquid environment and shock resistance and good airproof performance seal arrangement, to those skilled in the art, be the direction and goal extremely needing to strive for.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is to provide a kind of for the seal arrangement in liquid environment, reaches sealing effect by means of thread locking power between part and material deformation pretightening force.
(2) technological scheme
For solving the problems of the technologies described above, the invention provides a kind of for the seal arrangement in liquid environment, it is characterized in that: sealing device comprises and connects spiral shell, sealing spiral shell, Delay Tube, center tube and fill, described Delay Tube be connected spiral shell and be threaded, screw connection point painting sealer; Fill fills in center tube inside; Center tube one end self seal, its other end is sleeved on the A cylndrical surface of Delay Tube, by applying external pressure, center tube is out of shape, the B taper-face contact of its inwall and Delay Tube; Sealing spiral shell is screwed in by threaded engagement and connects on spiral shell, and the C conical surface extruding center pipe of sealing spiral shell, makes center tube be fitted on the B conical surface of Delay Tube, and the sealing C conical surface of spiral shell and the B conical surface of Delay Tube match, and screw thread position is coated with thread locking agent.
Wherein, described center tube adopts yielding plastic materials to make.
Wherein, the length of described center tube and diameter are determined needed for reality.
(3) beneficial effect
Compared with prior art, the present invention possesses following beneficial effect:
The present invention relies on Delay Tube and is connected the locking force that is threaded that spiral shell is spirally connected, seals spiral shell and be connected the material deformation pretightening force that spiral shell screws extruding center pipe by screw thread and reach seal isolation effect; effective solution cannot be loaded larger Sealing and seal limited structure in the confined space; effective insulation blocking can be implemented to inner member, be particularly useful for the sealing of water base grenade center blast assembly.
Accompanying drawing explanation
Fig. 1 is the structural representation for the seal arrangement in liquid environment provided by the invention;
Fig. 2 is the structural representation for Delay Tube in the seal arrangement in liquid environment provided by the invention;
Fig. 3 is the structural representation for sealing spiral shell in the seal arrangement in liquid environment provided by the invention.
Embodiment
For making object of the present invention, content and advantage clearly, below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1,2 and 3, provided by the invention for the seal arrangement in liquid environment, sealing device comprises and connects spiral shell 1, sealing spiral shell 2, Delay Tube 3, center tube 4 and fill 5, described Delay Tube 3 be connected spiral shell 1 and be threaded, screw connection point painting sealer; It is inner that fill 5 fills in center tube 4; Center tube 4 one end self seal, its other end is sleeved on the A cylndrical surface of Delay Tube 3, by applying external pressure, center tube 4 is out of shape, the B taper-face contact of its inwall and Delay Tube 3; Sealing spiral shell 2 is screwed in by threaded engagement and connects on spiral shell 1, and the C conical surface extruding center pipe 4 of sealing spiral shell 2, makes center tube 4 be fitted on the B conical surface of Delay Tube 3, and the sealing C conical surface of spiral shell 2 and the B conical surface of Delay Tube 3 match, and screw thread position is coated with thread locking agent.
Wherein, described center tube 4 adopts yielding plastic materials to make.
Wherein, the length of described center tube 4 and diameter are determined needed for reality.
So, the inside fill 5 that can realize center tube 4 is isolated with outside liquid.Consider toughness and the rigidity of material, this seal arrangement is not suitable with long center tube structure; Part material selects the consistency problem should considering itself and storage condition.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
Claims (2)
1. one kind for the seal arrangement in liquid environment, it is characterized in that: sealing device comprises and connects spiral shell (1), sealing spiral shell (2), Delay Tube (3), center tube (4) and fill (5), described Delay Tube (3) be connected spiral shell (1) and be threaded, screw connection point is coated with sealer; It is inner that fill (5) fills in center tube (4); Center tube (4) one end self seal, its other end is sleeved on the A cylndrical surface of Delay Tube (3), by applying external pressure, center tube (4) is out of shape, the B taper-face contact of its inwall and Delay Tube (3); Sealing spiral shell (2) be connected spiral shell (1) and screwed by screw thread, C conical surface extruding center pipe (4) of sealing spiral shell (2), center tube (4) is made to be fitted on the B conical surface of Delay Tube (3), and the C conical surface of sealing spiral shell (2) and the B conical surface of Delay Tube (3) match, screw thread position is coated with thread locking agent; Described center tube (4) adopts yielding plastic materials to make.
2. as claimed in claim 1 for the seal arrangement in liquid environment, it is characterized in that: length and the diameter of described center tube (4) are determined needed for reality.
